Abstract

The main aim of this project is to use the gLAB program to analize the data generated
by some GNSS receivers. The program gLAB was created by the GAGE/UPC research
group, with the purpose of offering an easy to use tool to the students who want to get
more deep knowledge on GPS, as well as to professionals who need precise positioning.
In this project we will explain the program’s main characteristics in a theoretical way and
through examples where it is explained how to get a precise positioning of GPS receivers.
In this document we can also find the analysis of the different sources of error that make
the GPS system not so precise to be used in aeronautical fields, such as to know the
correct positioning of an airplane or to take off and landing guidance. Along the project I
have carrier out a series of experiments with the SPS and PPP processing strategies to
localize a ground station with a static strategy, and the route of a light aircraft with a GPS
receiver has been followed. For the latter case a kinematic positioning strategy was used.
To end up we explain how to plot these routes using Google-Earth
